This is more of a related question/request than a solution to the original
topic.
Sometimes there appear to be "distracting" landmarks in some slices that might
not contribute to a proper alignment.

I wonder if there a way of restricting the SIFT search so it only considers
points inside a ROI (or a set of those) to then apply the transformation to
the whole slices?
I guess that a not-too-elegant way of doing this might be to clear outside all
ROIS, perform the SIFT alignment then apply the transformation to the original
stack, but would that work (maybe the artificial edges that are generated by
the clearing outside the ROIs act as new features?), and how to do this?

Gabriel
